David, Thanks for your response.

About 15x slower, and very unreliable (timeouts etc).

That's a good point to look for.  Have now checked the real servers and the
virtual IP, all have their reverse DNS records still intact.
Have also tried swapping around the resolv.conf order to further test the
DNS problem theory.

Clutching at straws of what else to try.  All I can think of left is a
reboot of the director.
